Control Techniques of Induction Machines Drives
5.1 Introduction on Induction Machine (IM) Control
This chapter mainly deals with high-performance control techniques of IM drives. Control techniques of IMs can be divided into two main categories: scalar and vector controls. Scalar control is based on the steady-state model of the IM and therefore permits regulating at steady-state only the magnitudes and frequency of the stator voltages, currents, flux linkages, and electromagnetic torque. Since it does not act on the angular position of the space-vectors of the control variables, it does not permit the best dynamic performance to be achieved. On the contrary, vector controls are based on the dynamic model of the machine; they permit ...
